L flank swollen, esp at level of navel.Nofvr.(same thing happened a mnth ago also, but went on tmp sm for an oral surgery, and felt better until 2day) ?

3 doctors weighed in

Swelling of the flank can be looseness of the muscles, inflammation of the muscles, distention of the left colon (large intestine) with stool and gas (most likely scenario).

Or a tumor (which is unlikely to go away!). Hernias are rare in the flank. I would suspect a buildup of gas and stool; you may benefit from a fiber supplement like benefiber or a laxative like miralax (polyethylene glycol). Good luck!
